Apr 12 2026 APP 2.0.0-beta41 has been released !

It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 has been released which works much better and faster. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more...

Update on the 2.0.0 release & the full manual

We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

 

Still need to crop, if I use crop mode in integration?

Hi all @mabula-admin

Normally I use „full mode“ in 6)Integration, and subsequently crop the edges away to eliminate the dither/drizzle artefacts.

Now I needed to use „crop mode“, to reduce the TeraBytes of work files needed for my 1028 frames at drizzle scale 2.0 😉
--> Question: are the edges clean, or do I still need to crop the artefacts away?
(I checked visually: looks as if there are no artefacts)

Thank you and best regards.

Hi Michael,

Great question, if you use the crop mode and are sure that you select a field of view away of the edges were the artefacts appear, then the resulting integration should be artefact free for sure 😉

Using the crop does not create artefacts in different areas of the field of view when compared to full mode.

The artefacts that you want to avoid exist because of drizzle, the borders of the individual frame in combination with outlier rejection. Those spots will be the same, if you crop that away in the composition it should be gone 😉

Let me know if all is okay when you try it,

Mabula

Thank you, Mabula.

Yes, I tried ... and it looked okay, but I wanted assortment, before I do all the linear processing and stretching.
